Yuyu Hakusho 4 - Yoshihiro Togashi

A delinquent's gotta do what he's gotta do...in the afterlife. Yusuke Urameshi was a tough teen delinquent until one selfless act changed his life...by ending it. When he died saving a little kid from a speeding car, the afterlife didn't know what to do with him, so it gave him a second chance at life. Now, Yusuke is a ghost with a mission, performing good deeds at the behest of Botan, the ferrywoman of the River Styx, and Koenma, the pacifier-sucking judge of the dead. The legendary exorcist Genkai is about to pass on her explosive demon-smiting techniques to one student—and only one. Trouble is, one of the people battling for the honor is a demon in disguise: the sadistic Rando, who'd just love to turn Genkai's power against innocent humans... unless Yusuke can defeat him! Then, Yusuke and Kuwabara must stop a quartet of demonic criminals from plotting a supremely sinister attack on the mortal world. At the gates of a labyrinthine fortress swarming with monsters, demons, and supernatural fugitives, these two teenage punks don't stand a chance in Hell—unless they can call for backup...
